Seventy-one percent of the Earth's surfaceis covered by oceans, and our understanding of the oceans is much less thanthat of land. In the future, the development and utilization of the oceans willundoubtedly be a major trend in human economic activities, leading some topredict that the 21st century will be the century of ocean development. As weall know, ocean development relies on various specialized equipment, amongwhich conductive slip rings play a crucial role. As an internationally renownedmanufacturer of conductive slip rings, JINPAT has developed various types ofconductive slip rings for marine development equipment.

From the current level of engineeringtechnology, human ocean development activities can be categorized into severalmajor types: marine fisheries, marine energy exploration and exploitation,offshore wind and tidal energy development, deep-sea reliability, and deep-seaexploration. Taking marine fisheries as an example, in addition to varioustypes of fishing vessels, offshore aquaculture is also very popular worldwide.In the context of nearshore fisheries and aquaculture, specialized conductiveslip rings are needed for underwater robotic systems and underwater monitoringequipment reels. Based on the slip ring cases provided by JINPAT, theseproducts include high-protection conductive slip rings and high-techoptical-electrical integrated slip rings.

Compared to the scenarios of fisheriesactivities, the conductive slip rings used in the marine energy extractionindustry are much more complex. Taking offshore oil drilling platforms as anexample, they require a variety of equipment that uses conductive slip rings.The conductive slip rings used on different equipment vary greatly. Forinstance, the deck cranes require conductive slip rings with high powertransmission capabilities, which must also meet the explosion-proofrequirements specified by national standards for offshore oil drillingplatforms. Besides drilling platforms, integrated slip rings in the mooringsystems of offshore oil refineries and FPSOs are also high-tech products.

Deep-sea exploration equipment primarilyuses integrated conductive slip rings. They are usually installed in thecontrol centers of research vessels to transmit signals and electrical energybetween deep-sea detectors and the mother ship. The signal modules in theseintegrated conductive slip rings generally use multi-channel fiber optic sliprings, and single-mode fiber optic slip rings are used to transmit signals overlonger distances. Similarly, to transmit electrical energy to depths of severalkilometers in the deep sea, the working voltage of the conductive slip rings isalso designed to be relatively high. This design greatly reduces the currentpassing through the conductive slip rings.
